how can i send 1kb over ble nus?

[luiskjuarez]

i have a problem with ble_nus_send_string  function, the BLE_NUS_MAX_DATA_LEN is 20 bytes but i need to send 1kb  every second, is that possible? i tried to put ble_nus_send_string with 20 bytes chunks within a cycle but the connection is loss between the nrf52832 and the phone, without the cycle the phone receive the data correctly.

Hi luiskjuarez,

You should try to debug your application, see what where in the code it hangs and what error code is called.

(set breakpoints in APP_ERROR_CHECK and also enable RTT in the sdk_config.h and open the RTT terminal to get extensive information)

- Similar thread

- (old thread, but shows how you can split your data in to chunks and send out large amount of data)
